The largest sections on the geologic time scale are Precambian (which includes the Hadean, Archean and Proterozoic frames), the Phanerozoic (which includes the Palaeozoic, Mesozoic [the well known dinosaur era] and the Cenozoic [the most modern time frame]). After that, take your pick of the smaller subsections of the time scale for the last one. No, actually the answer above states three eras. There are 4, the Precambrian, the Paleozoic with Cambrian, Ordovician, Silurian, Devonian, Carboniferous periods, the Mesozoic with the Triassic, Jurrasic and Cretacaous periods and the Cenozoic with Tertiary and Quaternary.

What are four large section on the geologic time scale called?

How many eons are there?
There are four eons dividing the geologic scale. Three occurred during the Precambrian era.
How do scientist contribute to the geologic time scale?
Paleontologists search for fossils to help them to determine what types of organisms lived in the same locations and at the same time. They use major changes in the fossil record to divide geologic time into large chunks.The geologic time scale is divided into: eons (biggest), eras, periods, epochs (smallest).Earth's history is divided into four major periods, from oldest to most recent: Precambrian, Paleozoic, Mesozoic, and Cenozoic
How many eras make up the geologic time scale?
Four eras. that is Cenozoic,mesozoic,paleozoic and precambrian
The 4 eons of the geologic time scale are?
Four eons comprise Earth's geological time scale. Other time intervals of the Earth are eras, periods, and epochs.
A symphony is a large scale orchestral work usually in movements?

What is a division on the geologic time scale?
The divisions of the geologic time scale are divided into four eras. from earliest to closer to the present is the Precambrian, Paleozoic, Mesozoic, Cenozoic. During these time periods, there were several major evolutionary events. Most commonly known are the dinosaurs and humans. Hope that helped :)
What are the major time intervals represented by the geologic time scale?
The Geologic Time Scale is divided up by four major intervals. In order from Largest to smallest: Eons are the largest time frame covering hundreds of millions of years. Eons are divided into smaller time intervals known as Eras. Eras are subdivided into Periods. Periods are broken into finer subdivisions known as Epochs.
